JAMES W. HALL, OF DUBLIN, INDIANA, ASSIGNOR OF ONE-HALF TO JAMES F. HATFIELD, OF FOUNTAIN CITY, INDIANA.

SEED CLEANER AND SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 688,244, dated December 3, 1901.

Application filed November 26, 1900. Serial No. 37,795. (No model.)

To aZZ whont it may concern:

Be it known that I, JAMES W. HALL, a citizen of the United States, and a resident of Dublin, in the county of Wayne and State of Indiana, have made a certain new and useful Invention in Seed Cleaners and Separators; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a perspective View of the concave imperforate trough K. Fig. 4; is a fragmentary section illustrating the relative positions of the deflectors for obtaining a straight outdraft between the shoes.

This invention has relation to certain new and useful improvements in fanning-mills or 'seed cleaners and separators; and it consists in the novel construction and combinations of parts, all as hereinafter described,and pointed out in the appended claim.

Referring to the accompanying drawings, the letter A designates the frame of the machine, and B B the upper and lowervibrating shoes thereof, carrying the screens,and which are supported and slide upon rollers 19 b.

The fan-casing O has a rearwardly-extend in g discharge-passage D, and arranged in this passage are the blast-deflecting boards E and F, which may be arranged in the form of a hopper, as in Fig. 2, to receive the seed which has passed through the screen or screens of the upper shoe and deliver to the screens of the lower shoe. The forward board E is hinged at one end thereof at the upper extremity of the outlet from the fan-casing forming the roof or cover of the blast-discharge passage and is arranged to be brought at its opposite end portion against the lower wall of the discharge-passage some distance from such casing at the limit of its downward 1n ovement and to be supported at different elevations by the pin d engaging a series of apertures d in the casing. The lower wall of the discharge-passage is formed by an extension of the fan-casing at the lower portion thereof,

casing extension to concentrate the blast and to change the direction thereof to a more or less extent. The lower wall of the blast-discharge passage or its floor or bottom is formed by an extension of the fan-casing toward the upper end of the lower screens.

G G designate levers pivoted one at each side of the machine attheir lower ends and having at their upper end portions each an elongated slot g, in which Works a crank-pin g of a sprocket-gear H upon the fan-shaft to vibrate such levers. This vibratory movement of levers G G is communicated to the lower shoe by a transverse bracing and operating rod '1', engaging depending bars I of said shoe, and in order to vary the movement of the shoe to adapt it for different varieties of seed, series of registering apertures i 7: are provided in levers and bars, in which apertures the said rod is adjustable. The upper shoe is vibrated to the same extent as the lower shoe by means of the lever J, centrally pivoted to the fan-casing and connected to said shoes at its extremities.

In operation when the board E is raised about one inch with its support in the lowermost hole, as shown in Fig. 2, the blast strikes board F, which is pivoted at the outer end of the blast-discharge passage at its lower edge, part only thereof being deflected upwardly in a light lifting manner, as used for timothy, redtop, and the like, which require very careful handling, by which process the light chaff, &c., is lifted out from below. When the air-board E is raised with its support in the second hole from the bottom, or two inches, the blast strikes board F from its center downward, is stronger, and is used for clover-seed, millet, and the like, which are heavier than timothy. When air-board E is further raised with its support in either of the three upper holes, a full blast is thrown against board F and is deflected upwardly in a consequently stronger stream for use with wheat, oats, corn, 850. At the same time with the above adjustments of board E board F, which is intermediately pivoted upon rod f and secured in its adjustment by thumb-nutsf' upon said rod, may be adj usted to send more or less of the blast downwardly or upwardly, or a straight-out blast may be obtained, as shown in Fig. 4. It will thus be seen that the two air-boards may be adjusted so that the entire blast may be directed'downwardly at different angles or upwardly at difierent angles, or that such blast may be directed downwardly and upwardly at the same time, or the entire blast may be directed straight out between the shoes or partly straight out between the shoes.

It will be noted that by my devices for vibrating the shoes, a long slow oscillating motion may be given them for use with wheat or the like, a short quick oscillation may be given them for use with all varieties of grassseeds, or that median degrees of movement may be given the shoes for use with other varieties of seed, thesame movement being also given the upper shoe by the devices already described.

The upper or chaff shoe, at its end adjacent to the hopper A of the machine, has a transverse imperforate concave sheet-metal trough K located directly under the hopper, the seed passing from such trough to the screen. The seed delivered to this trough is oscillated therein through movement of the shoe, and in such oscillation any oats present in the seed will be arranged lengthwise of the trough and so discharged therefrom upon the screen, progressing therealong with their greatest lengths arranged transversely of the screen, whereby the cats is prevented from tipping up and going through the screen, which it will do if progressing with their greatest lengths longitudinally of the screen.

The frame A has upon each side thereof the two vertical bars A, the long floor-bar A c and the two bracing-bars A extending obliquely from the extremities of the floor-bar to the vertical bars. A cross-bar A connects and braces the two vertical bars upon the inside aud provides a support for the fan-shaft bearings.

The machine is operated by crank H of large sprocket-wheel H connected by chain H to small sprocket-wheel H.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a seed cleaner and separator, the combination of the upper and lower vibratory shoes and screens, the fan, and fan-casing, the lower wall of said casing being extended at an inclination toward the upper portion of the lower shoe, the adjustable blast-deflector pivoted at the upper portion of the blast-exit from said casing, and acting in conjunction with said casing extension to concentrate the blast, the second adjustable blast-deflector pivoted between such shoes, the levers pivoted at the lower portion of the machine, and having an operating connection at their upper end portions with the fanshaft, the depending bars of the lower said shoe havinga transverse bracing and operating rod connection with said levers, and the operating connection between such upper and lower shoes, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES WV. HALL.
